Dark toxicity of DEX6ss nanoparticles. Dark toxicity of DEX6ss nanoparticles was evaluated with HCT116 cells in the absence of light. Ce6 or DEX6ss nanoparticles were exposed to cancer cells for 2 h, washed with PBS, and incubated for 24 h. The presented data was mean ± s.d. from 8 wells of 96-well plates.
